Spell to Banish Negative energy?

I know that depression isn't anything to ignore, with that said.. I also believe that medicine isn't always the answer to everything. This may sound a little weird but, mix a few drops of rosemary and lavendar oils in some water, put in a spray bottle. Then walk around your home and spray it. While doing so say a chant that you've come up with. It does help. Also, if you can't do that find some really good soothing music and play. It will change the energy in your house also.
